Actually send this blog feeling is not what to use, too simple, will people disdain to see, will not be a person's own brain also thought of. But look at their own blog has been so long no more, really distressed ~. A rough calculation of only the code of hydrology, will occupy the OSC at least more than 10 KB of database space, but, the thought of Luantan in the egg, also relieved. This is a very classical probability algorithm function:

1. Multiply the 17 digits of the previous ID card number by different coefficients. The coefficients from the first digit to the second digit are: 7-9-10-5-8-4-2-1-6-3-7-9-10-5-8-4-2.2. Add the result of multiplying the 17-digit number and the coefficient.3. How much is the remainder can be seen by adding and dividing by 11?4. The remainder can only contain the 11 numbers 0-1-2-3-4-5-6-7-8-9-10. The numbers of the last ID card are 1-0-x-9-8-7-6-5-4-3-2.5. If the remainder is 2, the X of the Roma
